We are making the transition from prototyping to fabrication. It's time to (finish designing and) build a robot.
Mechanical Fabrication
- Pivots
- Complete cutting and key the 7075 Al transfer axles
- Key and cut retaining clip groove into 4140 steel co-axial drive shafts
- Fabricate angle sensor mounts
- Key 32T Al pulleys (1" diam)
- Chassis
- Complete gussets
- Finish welding Deux
- Start welding Prime
- Slingshot
- Complete rough cutting 1 x 1 square tubing
- Finish square tubes with non-square ends
- Cut gussets
Design
- Layout basic state logic with programmers (Siri, Julie - draft done)
- System-level ball routing, ball auto-ejection, manipulator tensioning
Programming / Control
- All programming team members need to install LabVIEW and FRC software on a personal computer (see DEWBOT_X_Programming for details) -- Make sure FRC 2014 appears when starting LabVIEW
- All programming team members need to complete the certification test
- Position and angular error spread for autonomous movement (by revolution counts) via testing procedure (Pat, Julie, Siri - procedure documented)
- Tweaks to keep in mind for tach-based autonomous driving (kept here as reminders for any new code):
- Wheel initialization -- e.g. rotate 360 degrees (no shortest distance), then back 180 degrees
- Ramp up drive power based on revolutions reported by encoders
- Gather tach-based autonomous driving trial data -- FOR EACH COMPETING ALGORITHM
- Should still compare two versions: tach-vs-tach and tach-vs-expected ?
- Tweaks to keep in mind for tach-based autonomous driving (kept here as reminders for any new code):
- Demonstrate move to/wait for Hot Goal -- N/A?
- Demonstrate dashboard-to-robot-code communication -- HIGH PRIORITY
- Design dashboard layout with drive team -- HIGH PRIORITY
- Finish translation of automated tasks strings into motor/solenoid commands -- HIGH PRIORITY
- Autonomous sequence needs to be implemented
- Typical "primitives" approach is not going to work
- CODE REVIEW on Wednesday -- All available programming team members should participate
Scouting
- Layout preliminary match and pit UI sheets and Excel/Tableau files
- Lock down prioritize (first generation) metrics
PR
- Paint more hats
- Plan/start videos (at least release video)
- Vests and sweatshirts
Welding
- Build a shelf storage unit for the welding area giving welding team much needed practice.
- We've been using alloy 4043 for all our robot welding. However, alloy 5356 may be a better choice. It is more ductile and stronger especially in
shear, which it what many of our chassis joints are subject to. We need to devise a simple test to evaluate.
- Weld pivot tubes to pivot tops
